DSWaitForJobList

[freef1yer]

Hi Everyone

I've been having some trouble trying to get the DSWaitForJobList function working, which results in the following error:

Code: Select all

0610    Return Value = DSWaitForJobList("Add", singleStreamJob, 1);
               ^
Variable Name (UNDEFINED) unexpected, Was expecting: ';', End of Line

The documentation suggests that the second argument of the function (singleStreamJob above) should be a handle, but gives an example of it quoted as a string, as follows:

rtn$ = DSWaitForJobList("Add","Function Err",1)

Does anyone have experience of using this?

Thanks

Dave

If your code example is literally what you are trying to run, the problem is the whitespace in your variable name. Try it using "ReturnValue" instead of "Return Value" and you should be ok... or at least more ok.

Doh! Sorry...... abstracted it a bit and managed to put another bug in.

The real error is this.....

Code: Select all

0611    ReturnValue = DSWaitForJobList("Add", singleStreamJob, 1)
                                                          ^
',' unexpected, Was expecting: '!', ')', '=', "AND", "OR", "LT", "LE", 
"GT", "GE", "NE", "EQ", "MATCH"
Array 'DSWaitForJobList' never dimensioned.

Thanks

Where do you find DSWaitForJobList in the documentation? I find DSWaitForJob but not the one you use. From the error message I would think DataStage does not think the DSWaitForJobList exists as well.

That was a new one on me, too. Found it in the BASIC reference. Not sure how to utilize it... all I've managed to do so far is duplicate the original problem.

"Array never dimensioned" errors usually mean that you've forgotten to include a DEFFUN declaration for a function.

When the compiler encounters an identifier followed by a left parenthesis it assumes - because it's not been informed that the identifier is a function name - that the identifier is the name of a dimensioned array, it then checks through it's list of array structures and fails to find the DIMENSION statement.

I've just checked on a DataStage version 5.2 system. There is no supplied DSWaitForJobList function here.

Therefore, if you do have it, and it's compiled, it's in the "user written functions" part of the repository, so your DEFFUN declaration must refer to "DSU.DSWaitForJobList".

Code: Select all

DEFFUN DSWaitForJobList(Arg1,Arg2,Arg3) CALLING "DSU.DSWaitForJobList"

Thanks for the input guys.

This isn't a user-written function, it's a supplied function I found in the documentation, but which apparently doesn't exist (thanks Ray for confirming that).

FYI The documentation I found it in is online help on DataStage 5.2.2.

Thanks

It's even there for DS 5.2.1 (in on-line help), so maybe it's an intrinsic function for job sequences. I'll have to do more investigation.
However, re-reading your error message, the caret isn't under the DSWaitForJobList token, so it's probably not that.
